RD Sharma Solutions Class 12 Differentials Errors And Approximations

RD Sharma Solutions Class 12 Chapter 14

Let \(y=f(x)\) be a function of x, and let \Delta x be a small change in x and \(\Delta y\)  be the corresponding change in y. Then,

\(\Delta y=dy/dx\, \Delta x\) approximately

dy/dx \Delta x is termed as differential of y and is denoted by \(dy\)

Some of the useful result on differentials

  • If \(f(x)\) is a constant function, then its differential is zero.
  • If \(y=cu\), then \(dy=c\, du\), \(c\) is a constant.
